Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] An asphalt pavement effective compaction time test device, comprising a temperature sensor 4, a data acquisition instrument 5 and a stopwatch, the temperature sensor 4 is a Pt100 platinum resistance temperature sensor with an accuracy of 0.1°C, and the data acquisition instrument 5 is an XMD- 2000 multi-point itinerant detector, the temperature sensor 4 is connected to the data acquisition instrument 5 with a special wire 6, the wire 6 needs to be straightened as much as possible and kept horizontal, and the clamp between the temperature sensor 4 and the straightened wire 6 The angle is not less than 150°, and the wire 6 and the joint between the temperature sensor 4 and the wire 6 have been processed through high temperature resistance and rolling resistance, so that they are suitable for high temperature rolling operations; this device should also include a bra...

Abstract

The invention discloses a testing device for the effective compaction time of an asphalt pavement. The testing device comprises a temperature sensor, a data acquisition instrument and a stopwatch as well as a bracket, wherein the temperature sensor and the data acquisition instrument are connected through a lead, the bracket comprises a pointed-end rod and a slider, the slider is arranged on the pointed-end rod in a sheathed manner and provided with a fixed circular hoop, and the temperature sensor is inserted into the fixed circular hoop. Through the temperature sensor and the data acquisition instrument, the average temperature of the asphalt pavement at the to-be-tested position and the change law of the average temperature can be conveniently and accurately tested; by controlling the effective compaction time of paving layers of the asphalt pavement in the rolling process, scientific rolling can be conducted, the operation with manual experience only is avoided, and the requirements on the compactness and practicability of the asphalt pavement can be met to the maximum extent.

Description

technical field [0001] The invention relates to the traffic field, in particular to the technical field of asphalt pavement construction. Background technique [0002] Since the 1930s, the emergence and rapid development of high-grade highways have laid a solid and reliable foundation for economic prosperity. In the construction of high-grade highways, asphalt pavement is a seamless continuous pavement, because of its smooth surface, comfortable driving, wear resistance, small vibration, low noise, short construction period, easy maintenance and repair, suitable for phased construction And recycling and other advantages, more and more countries around the world pay attention. Since the 1950s, the number of countries building asphalt roads has increased rapidly. In my country, since the construction of Beijing-Tianjin-Tangzhou Expressway, asphalt concrete pavement has been the main structural form of high-grade highway engineering, and has been greatly developed. At the sa...
